Thanks Idun.. It seems to be what I've 'heard'..
In truth, the UK 'rule' is probably not far off this but people tend to take as much as they can..
When I got a fine, I was definitely on a red light, so fair enough. I was stressed with a heavy load sticking out of the back of an estate car, and I was paying more attention to looking in the rear mirror than the lights..
So you er on suggesting your visitors to not slam on the brakes on orange? It's a fine line - you could have crossed with your front wheels just as you notice in the corner of your eye the light change from green to orange.. Then what? Split second decision the check no one is 10cm off your rear and arrête!
I'm truly paranoid, especially at that particular light, and even take detours to avoid it!
